2 cameras the same. 2 different colours

[Vauxfan]

Both ds 2cd2347g2 lu cameras.
The image of the front garden shows the car on the right as green. This is the true colour.
The second video shows this car as white.
Both images are at night with no white light. The light comes from a street light. Is this normal for the colour to be so far out? Sunlight also makes the image bright losing clarity in colours on the camera.

Hi @Vauxfan

Camera position and the light & shadow in the camera's FoV have a massive effect on the performance of a camera.

I can see that with the side camera the sensor is struggling with the brightness in the background and darkness in the foreground and this is probably because the camera is adjusting its sensitivity to try and give you more detail in the darkest areas of the image but this adjustment is applied across the whole image and thus bright areas get brighter and start whiteout.

The camera isn't having to adjust its sensitivity so much at the front of the house because the lighting is much more even across the whole scene.

You can play around with the cameras image settings to try and get a more similar result from both models, you can use settings like HLC (High Light Compensation), BLC (Back Light Compensation), and WDR (Wide Dynamic Range) to adjust the way the camera handles contrasts in light.

You can also play around with the Exposure Time, by default most of the ColorVu models have their exposure set to 1/12 which is slower than the traditional 1/25 but this slower exposure allows more light into the sensor for brighter images. I would recommend playing around with slower & faster exposures in combination with the HLC/BLC/WDR settings and see what gives you the best results.
